I just downloaded Lady Byron's Fantasy lenses set from the freebies section and I just can't figure out how to apply them to my characters.

I have tried all kind of things in the material menu and the worse effect was that the eye texture was applied to the whole body....

And second thing, does anybody know any useful program that extracts zip files automatically files to right folders? Lots of nice people have build there zip files to extract in right folders but there is so many that I have to install manually and that is really boring and time taking job.
